EYEGLASSES.

Specification of Letters Patent.

Patented Oct. 1,1912.

Application filed February 14, 1908. Serial No. 415,808.

lb all whom it may concern.-

Be it known that I, LEO F. Apr, ofv the city of Albany, county of Albany, and State of New York, have invented certain new and useful Improvements in Eyeglasses; and I do hereby declare the following to be a clear, full, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to eyeglasses of the finger piece type in which the nose guards are mounted to swing on the support and are positioned by suitable springs and it has for an object to provide a construction having but a few simply adjusted parts, so that the labor of assembling and taking down the eyeglasses will be reduced to a minimum.

The invention is further directed toward providing improved springs for positioning the guards that will have a maximum degree of resiliency and will be so placed and connected to the respective parts against which they act as to offer certain conveniences in both applying and removing them.

To these and other ends the invention consists in certain improvements and combinations of parts, all as willbe hereinafter more fully described. the novel features being pointed out in the claimsat the end of the specification.

In the drawings: Figure 1 is an enlarged View of an eyeglass constructed in accordance with and illustrating one embodiment of my invention; Fig. 2 is a top view of the same embodimcnt; Fig. 3 is a bottom view; Fig. 4 is a central transverse section; Fig. 5 isa section on the line 2-2 of Fig. 2, and Fig. 6 is a perspective view of one of the nose guards.

Similar reference numerals throughout the several figures indicate the same parts.

In both illustrated embodiments of the invention the lenses A are rigidly connected by'a support bridging the nose of the. wearer and the nose guards are mounted to swing on the support toward and from the nose.

In Figs. 1 to G-the support consists of a bridging portion 1, integral with the lens attaching devices 2, and preferably has its upper surface formed wit 1 horizontal seats 3 near the lens attaching devices. On these seats are mounted the nose guards or finger piece levers which swing substantially in a pair of the eyeglasses and the substitution of horizontal plane toward and from the nose .at their rear ends and have upper and lower nose engaging pads B and C located at these points.

Each guard is moved toward and from the nose by a coilspring 7 preferably of fiat spiral form, arranged in the present instance below the support with its axis vertical and coincident with theturning axis of the guard. The springs are preferably carried by the guard so that when the latter ar removed from the support the springs will be carried on them, thus facilitating the re.

guards of other sizes andhformations to fit individual noses. In the present instance, each spring is formed in one piece with portions. of the nose guard in order, among otherreasons. to reduce the number of parts to be handled and the conspicuousness of the eyeglasses and for this purpose the levers which project longitudinally forwardly and rearwardly from the plane of the lenses and carry the bearings 4 and nose bearing p0rtions B-O form, in each instance, one arm of a loop 8 and the other arm of such loop is extended downwardly toward the plane of the spring coil and merged into the outer end or the outer convolution thereof which thereby forms a'cont-inuation of the lever. The material from which both parts are pro duced is preferably a ribbon of fiat stock and the bend both at the loop 8'and at the point of connection of the guard and coil are in a fiatwise direction for purposes later referred to. i

The springs interlock with the support in a manner to retain-the bearings 4: of the guard in engagement with the bearing 5 of the support and for this purpose there are employed interlocking connections ea'ch preferably consisting of a shoulder 9 below the bridging portion carried by the latter and an arm 10 extending rearwardly and outwardly from the inner end of a coil across the latter or in other words from an inner convolution across anouter convolufree end in engagemen tion and held at its with the adjacent portlon of the support, 105

above the shoulder, by the spring action of the coil.

In the specific structure shown the shoulder 9 is constituted by the lower hooked end of a depending free arm on the support extending through the plane of the coil exteriorly thereof, as shown, and independently of both the bridge and lens attaching portion so that a proper engagement is oflered the spring whatever change may be made in the positions of theseparts. By also bending the inner spring arm l0 flatwise of the stock and disposing. its flat side against the face of the coil that it crosses, I make it hug the coil very closely so that it is not necessary to bring the shoulder 9 down very far in order to cooperate with it and the vertical extent of. the spring in the direction of its axis is materially condensed to which end the other flatwise bends previously referred to, contribute. It is advantageous to run the arm 16 radially or diametrically from the far side of the inner convolution, as shown, so that it passes through the axis, one of the reasons of this being that the inner convolution' is thereby flexed'inwardly toward the center rather than otherwise with the result thatthere is no tendency for it to prevent the free inward flexing or contracting of an intermediate or outer convolution.

Referring back to the fiat disposal of both ends of the spring it is furthermore pointed out that by thus arranging them as nearly identical in extent with the plane of the coil as possible there is little tendency on their part to distort the coil as a whole from its plane of flexing movement, but to further provide for holding the coils against lateral displacement, projections 11 extend beyond the under surface of the support into the respective coils and are in this instance each formed in one piece with a pivot pin 5.

In operating the eyeglasses to remove them from the nose or fit them thereto, the forwardly. extending operating portions of the guards are pressed together, thus causing a separation of their nose bearing portions, and when the operating portions are released the guards move toward each other under the action of the springs. The guards may be removed from the support by lflOV-' ing the arm 10 from above the shoulder, and then disengaging the bearings 4: and

Eyeglasses constructed in accordance with this invention are inexpensive to manufacture owing to the fact that the number of parts is reduced to a minimum. The fitting of the eyeglasses by the Optician is facilitated because but a few manipulations are required to mount and remove a guard and its spring. The support may be adapted to different noses and to different pupillary distances, and the means permitting this result does not render the eyeglass conspicuous. Particularly is the attachment and (l tachment of the spring facilitated as the free radial arm is easily engaged or disengaged and the spring is applied when not under tension and later placed under tension.
